The BigQuery Tiler is a tool developed by CARTO, allowing for quick and easy visualization of large spatial datasets in BigQuery. This technology enables users to analyze global datasets on indicators such as population health facilities and mobility, without the need for significant computing power or resources. By partitioning large datasets into vector tiles, users can efficiently view data at various scales, including country-wide granularity. The tool also allows for analysis layers to be built on top of maps, enabling users to filter out areas with existing access to health facilities and focus on vulnerable populations. This technology has the potential to be applied across various use cases and datasets, making it a valuable resource for groups without technical expertise or resources.
